To reduce spam while keeping C4 competitions open to all, submission numbers are capped on a per-competition basis, using a set of reputational criteria:
signal determines the maximum number of submissions wardens/teams can make to each audit.
The higher your signal , the more submissions you get.
Low- or no-signal users' submissions are capped, to disincentivize spam and encourage newer wardens to focus on their highest-risk, highest-quality findings.
Unrestricted submissions unlock at 0.4 (40%) signal + verified identity/tax info.
Earn bonus (or uncapped) submissions by verifying your identity and submitting your tax information.
